ABSTRACT:
A soybean whey liquid is obtained by extracting water soluble constituents from defatted soybeans with water, precipitating proteins at the isoelectric point with acids and neutralizing the resulting supernatent liquid with an alkali.
This soybean whey liquid contains a very small amount of vitamins and unknown growth factors as well as sucrose, stachyose, water-soluble proteins and minerals. When a culture medium of the soybean whey liquid having sugars added therein is used for the culture of the bacterium Xanthomonas campestris, Xanthomonas polysaccharide is obtained with good yield.
